Fig. 10 is a longitudinal sectional view on the line 10-10 of Fig. 9; and

Fig. 11 shows an elevation of one 'of the locking levers after it has been released.

The automobile truck, designated generally by the numeral 15, comprises a supporting frame having longitudinal side frame members 16 of channel form connected by suitable transverse frame members. A

supplementary frame 17 is seated on the side frame members 16, the supplementary frame comprising lon itudinal side frame members 18 of c annel form and transverse frame member 19. The members 1S are secured to the longitudnal frame'members 16 by vertically extending cleats or plates 20, which are riveted thereto. The auxiliary frame 17 is adapted to be mu'nted on the underframe of* substantiall any automobile truck. The auxiliary rame 17 has mounted thereon a plurality of transverse supporting members 21 of channed form, which are arranged in pairs with their flanges directed away from each other, the lower flanges being riveted or otherwise secured to the longitudinal frame members 18. The transverse frame members 21 project beyond the lateral edges of the frame 17 and have mounted between them the rollers 22, which are supported bypivot pins 23. These rollers are adapted to coact with the lower flanges 24* of track or rail members 24 of Z-bar form, which are arranged in pairs with their lower flanges 24* directed inwardly and with their upper flanges riveted or otherwise secured to the floor 26 of the truck body 25. Each pair of members 24s.,...

lits loosely between a pair of members 21,

-thereby preventing movement ofthe bod suitable locking means.

. the fixed side wall 27, the ends of the wall 32 being adapted to seat against the ends of the end walls 29 and 30. The side wall 32 is provided at its ends with flanges 33 adapted to overlap the end walls of the body,

and this movable side wall is mounted to swing'gabout its lower ed e by means of hinges 34 comprising reliitively movable hinged members 34a and 34 secured to the side wall and to the underside of the body, respectively, sothat when the side wall is swung downwardly and outwardly, as

illustrated in Fig. 5, the lower edge of the' side wall 32 maintains a close connection with the edge of the bottom 26. y

The ends of the transverse frame members 21, at the right hand side ofthe car, have depending brackets 35 riveted or otherwise secured thereto.A (Iliesei brackets are pivoted by =pins`36 tothe door operatingl arms 37 which extend upwardly. at the side of the movable wall 32, and-are provided with longitudinal slots 37 adapted to be engaged by pins 38 which are carried by brackets 39 secured to the transverse track members 24. The upper or outer ends of the levers 37 have rollers 41 mounted thereon to coact with the wear plates or tracks 42,` which are secured to the outer sides of the 'le wall 32. 'When the body 25 is moved transversely of the frame to the inclined dumping position shown in Fig. 5, the pins J8 move outwardly to the outer ends of the slots: 37, while the rollers 4l move downwar( ly on the plates 42, thus allowing the sideidoor or wall 32 to swing about its hin ies to the inclined dumping position in ainement with the floor 26, as shown in Fig. 5, in which position the door is supported by the levers 37. The opening movement ofthe door is limited by the pins 38 engaging the ends of the slots 37a. W'hen the body is returned to its normal position above the supporting frame, the levers 37, sliding on the pins 38, automatically return the side door 32to its closed position and hold it in that position, as shown in Fig.- 4.

The tilting movement of the body 25 is controlled by a plurality of guidin members 45, one of which is mounted vetween each pair of transverse frame 'members 21. Each guiding member 45 `is provided at its upper end with a transverse pin 46 adapted to engage one Aof the slots 47 in the track members 24, which are secured to the under side of the body. These track members are v reinforced around the slots 47 by the slotted members 48, which are secured to'the memprovi ed with a curved slot 49 adapted to' be engaged by a pin 50 supported between the transverse frame member 19 andthe bracket 51 secured to a transverse frame member 21. Each controlling member 45 js further provided on its outer 'side with a curved surface 45a which is adapted to coact with the rollers 52 carried bythe brackets 53 secured to the longitudinal frame members 18. In the operation of dumping the body, it is first moved toward the right, as viewed in Fig. '4,jnntil the pins 46 occupy positions at the left-hand ends of the slots 47, whereuponfthefze'ontinued operation of the actuating/mechanism causes the body to tilt upwardly. The pins 50 then travel -in the slots 49 and the controlling members 45 travel on the rollers 52 as the body tilts over the edge of the/supporting frame. The tilting of the body is limited by the engagement of, the pins 50 with the lower ends of the SlQtS'49.

The movement of the body 25 toward the right, and the tilting movement thereof are Aeffected by means. of a sha-ft 55 which extenua'longitudinally of the auxiliary frame 17 and issjournaled in bearings '56' carried by'q the ends of the transverse frame members 21, as shown, for example, in Fi s. 4 and. 5. The shaft is provided between tie airs of supporting members 2l at the forw' rd and rear ends of the body with driving pinions 57, which are secured to the shaft and adapted to engage raclr bars 58 secured to the.

brackets 59 carried by and between the track members 24 on the underside of the body. A roller 22 is mounted on the shaft 55 between fthe middle pair of supporting members 21.

The rollers 60 arerotatably mounted on the shaft 55 onopposite sides of each pinion- 57, and these rollers coatt with the lower flanges of the track members 24, similar to the o eration of the rollers 22 previously descri ed. The shaft 55 also has rotatably mounted thereon. between one ofthe rollers 60 and each pinion 57, `a holding member 61 which carries on the upper pzxrt thereof a pivoted roller 62 adapted to coact with the upper sideof the Harige 24 of the adjacent track member. As-the shaft 55 rotates the inions 57 engaging the rack-bars `58 cause t ie truck body to move to the right as viewed in Fig. 4, and after the limit of the horizontal movement has been reached the body begins to tilt and finally assumes a pivotal movement about the axis of theshaft 55. During this pivotal movement the body is held against upward movement with respect to the supporting frame by .means'of the holding devices'61. pon rotation of the shaft in the reverse direc"- tion the pinions 57 co-ope'rate with the rack-bars 58. to return the body to its normal horizontal position.; 1 I i The shaft 55 is driven by a parallel shaft which is journaled in bracket 66 secured to the longitudinal side frame member 16 of the truck. This shaft 65 has sprocket wheels 67 carried thereon between the arms of the bracket 66, and the sprocket chains 68 lconneet the I sprocket wheel 67 with "ifther sprocket wheels 70 which are 'Y ured to the shaft 55. Adjacent the forwa end of the body of the shaft 65 is exieidedinto 'a housing71 and is there connected with a trainsverse driving shaft 72 through beveled gears 73 and 74. The shaftl 72. is journaled in a bearin 7 5 and the other end thereof carries a 'fi beveled friction. disk v76'ada ted to coact with either of two beveled 'ction -disks- 77 and 78, which are secured on the longitudinally extendin shaft 79,'. 'The shaft 79 extends forwa ly from the shaft and a gear-80 keyed there'oumeshes with a gearf811secu'red 'on thef lowershaft' 82 of tha-transmission? mechanism '-83,1.so that the shaft 79 'isconstantlydriven when the Y transmission shaft 82 is in operation.; 'The beveleddisks 77 and 78 arefspaced apart so that when 1the'shaft 79' is in its neutral position zfneit-her of thesedisksjwill coact with thef' friction disk 78,-bnt `u n move ,"men't-v :ofthe 'shaft vdS-'longitudiria ly -one "Q y'the disks77-or178 -will .be brought intoi'le; gagenie'ntwith the disk 7 6, thereby voperati-' in the shafts 72,. '(65 and 55 tomove the body of the truck in the desired direction. The reciprocation ofthe longitudinal shaft` y 7 9 is effected by means of a shaft' which carries a dog 85 adaptedto'eiigage a grooved collar 86 mounted on the' shaft4 7 9.. The

"shaft 84 extends transversely of' 'the frame and'is rotated simultaneously with the oper- 'ation of mechanism for locking the body fposition on the` frame. lThe shafts 79, and

84 are journaled in bearings carried by supp porting members 88 secured to the main truckframe.

The locking mechanism abovegreferred to comprises a 'series of locking levers or hooks -90, which are vpivoted on pins91 secured to A and extending between the pairs of track f members 24. The members 9,0 "are provided with hooked extremities' adapted toengage@ the longitudinal shaft '92,A which extends.

throughout the length .of4 the car, beingmounted in bearings formed'in the 'projecti ingy ends of tlie'firame members21 at the'` I. ends thereof opposite the shaft 55. VThe downward movement Tof each hook is lim.- ited by a pin 93 extending between the members 24 and when 'the operator desires to release the `bod'y to permit the dumping movement thereof the shaft 92 is rotated, thereby causing the dogs 94 securedV thereon to engage the ends of the hooks 90 and elevate 70 95 secured tothe forward end thereof and75 attached to a downwardlyextending link 96. The link 96 en ges one 'ann of a bel crank lever 97 and t e other arm of this lever is pivoted to1a connectin 'rod 98j.whieh extendsforwardl lat the side of the frame and 8 is attached at-its forward end to the upper extremity of a crank arm 99 which is secured to' the'transverse rod or shaft 84 pneviously described. From the upper extremity of the crankarm 9.9 an operating rod 100 85 extends in a forwarddirection and is connected toan operating lever 101 pivoted on the side frame member 16 and adapted to be held'.in the desired -position by means of allath!V 102 engaging a notched bracket 103. 90

the l'e'v'er 101 is moved in a forward direction the dogs 94 `are elevated, thereby raising the hooks 90 out of engagement with the shaft 92 and'relea'sing'the body., At the same' time the angular movement of the 95 Shaftf causes, the friction diskA 77 to en- "gagtlife ldiskf 6 and thereby drive the shafts 72 and 65- i the (proper direction'to move the body toward umping position. When the leverA 101 is moved in a rearward direc- 100 tion the do 94's are, lowered to the position shown inv f4, and at the same time the shaft 84 is operated .to .move the otherv friction disk 78 into engagement with the disk 76. The shafts. 65 and 55 are thereupon op- 105 erated to returnsthe bod to its normal horiv`zontal position above t'e'frame and, as it reaches the .limit of this movement, the inclined end faces of the hooks 90 ride up over the shaft 92 until the hooks engage that 110 shaft. .The pins 93,previously referred to 'holdthe hooks 90 in proper position to enlgage-the shaft 92 when the body returns to. its normal position. The limit ofg'the return movement of the bodyis determined by hooks 104 which areA secured tothe upper sides of the frame members21 and engage the transverse pins. 91 upon which the hooks 90 aremouiited...

From the foregoing understood that-the body is positively moved to and; from its dumping position by means of the power ,connections which extend to vthe transmissionfshaft of the truck.. The

movement ofwthebody can be controlled by of Jtli e ':ar :and return the body to its normal position without leaving his seat. The lock- 1w Vdesmption n will beim ing and unlocking of the body is effected simultaneously with the actuation of'the power mechanism, so that the entire operamovement thereof has been reached/As soon as the body begins to move horizontally towardsits dumping position the door-operating levers 37 are carried outward-ly about the pins 38, due to the fact that the lower ends of these levers are held by the supporting frame. As the. levers 3T swing outwardly the pins 38 travel outwardly in the slots 37* and the rollers 41 travel inwardly on 'the track members 42. so 'that the side door of the car is automatically supported as' itmoves to the inclined position shown -in Fig.

5. In this position the side door is held by.-

the levers 37 in alineinent with the fioor'of the body. lVhen the body is returned to its normal position by the reverse operation of' the driving pinions. the levers 3i' are automatically elevated by the pins 38 and the side door 32 is thereby positively returned to its closed position. l

Although we have shown and described a certain embodiment of the invention/for purposes of illustration. it will be linder- -stood that it lmay be constructed in various other forms without departing from the scope of the appended claims.
